' IMPROVEMENT IN BENCH-HOOKS AND CLAMPS.

Specification forming part rof Lett-ers Patent No. 48,498, dated June 17, 1865.

iiTo all whom t 'may concern:

Be it known that we, E. P. WOODS, of Lowell,

in the county of Middlesex and Stateof Mas-4 ence thereon, making part of this specification.

Of the said drawings, Figure lis a top view. Fig. 2 is an under-side view, and Fig. 3 an end view.

Similar letters of reference indicate like parts in all the drawings.

In the iinishing ofsinall work by carpenters, cabinet and pattern makers, and similar trades, much difficulty is experienced and time lost in effectually holding the stock iirmly for the plane, Src. j

The object ofonr invention is to obviate these difficulties; and our invention consists in the employment of two parallel bars, to one of which is attached a hook, the said bars being connected together' at or near the center hy a bar provided with a rack and'stop, as will be fully set forth.

To enable others skilled in the art to make and use our invention, we will describe the construction and operation thereof.

A represents a bar, which may be ot' any desired length, which is provided with two or more holes, a a, for dowel-pins to hold it to the bench.

B is another bar of the same length, one end of which is provided with a hook, E, to hold thepieceof stock. Thesebarsmayberabbeted together or not, as desired, and they are clamped together by a bar, U, hinged tothe piece B at b. This bar has an internal rack, D, in which is a pin, c, which isof proper size to catch in the teeth ofthe rack and hold it in any position, while the button on the pin prevents thepa'rts from coming apart. The under sides of both bars are cut away, so that the bar O and screw b and pin c'will be above the plane of the under side, so that it will fit the workbench.

The operation will be as follows: The jaws or bars A B are adjusted, so as to receive the .material to be finished, by moving the bar B the desired distance, and then hooking the rack-bar C upon the pin c, and the piece ot' work is inserted in the jaws, the end resting against the hook E on the end, and as the plane is applied the piece is grasped and held firmly between the jaws.

The apparatus is readily adjusted for thick or thin pieces ot' material1 and a Wedge-shaped piece will be held as firmly as a straight piece.

We claiml. The jaws A B, in combination with the hook E and connecting-bar C, substantially as and for the purposes set forth and described.

2. In combination with the jaws A B and hook E, making the apparatus adjustable for thick or thin material by means ot' the rack D and pin c, or equivalents therefor, substan-` tially as and for the purposes set forth and described.
